IMPROVEMENT IN CROZlNG-MACHINES.

Specification forming part of Letters Patent No. 217,021, dated July 1,1879; application filed May 20, 1878.

To all whom' it may concern:

Be it known that I, OSCAR J. PENNELL, of WVilliamsport, in the county ofLycoming and State of Pennsylvania, have invented a new and usefulImprovement in Orozing-Machines, of which the following is aspecification.

Figure l is a top view of a part of my improved machinery. Fig. 2 is asection of the same, taken through the broken line m m, Fig. 1. Fig. 3is a detail side view of one end of the same.

My invention is an improvement in the class of crozing-machines in whichthe croze is cut by knives attached to a revolving head.

The improvement consists in mounting the cutter-head in a swingingframe, which is vibrated, to cause the cutter-head to act on the staves,by means of a treadle-lever and friction-pulley; and in making saidswinging frame adjustable in its hearings to change its radius, for thepurpose of enabling the cutterhead to move through the arc of a greateror less circle, and thus adapt it to cut a deeper or shallower croze, asrequired for staves of larger or smaller barrels or other casks; and inmaking the blocks or supports for the staves vertically adjustable, toenable them to be set higher or lower, according to the size of stavesbeing crozed.

A is a long and narrow frame, to one side of which is attached the endof another frame, B. To the side of the frame A, at one side of the endof the frame B, are attached two posts or standards, 0, to the innersides of which are attached two verticallyadjustable rests, D, tosupport the staves while being crozed.

To the end of the frame A is attached an upwardly-projecting bar, E, toserve as a stop and gage for the end of the stave to rest against whilebeing crozed.

The crozing is done by a cutter-head, F, the journals of which revolvein bearings in the inner end of the frame G. The side bars of the frameG are slotted longitudinally to receive the boxes H, which serve asbearings for the shaft I, the ends of which work in bearin gs J,attached to the side bars of the frame B.

The boxes H are secured in the slots of the frame G, so that the saidframe can be adjusted upon them to cause the cutter-head F to swingthrough a larger or smaller arc, according as larger or smaller stavesare to be operated upon.

The object of the adjustment of the bearings of frame G is to 'cause thecutter-head F to cut a deeper or shallower croze, and the latter usuallyvaries in depth according to the size of the cask.

The transverse middle of the stave requires to be in line-that is tosay, in the same hori- V zontal plane-with the axis on which the frame Goscillates, and hence, 'when the staves vary materially in width, theblocks D are adjusted higher or lower, to bring the middle of the stavesin proper relation to said axis of frame G, and thus prevent the crozebeing cut of unequal depth at its ends and middle, as would otherwisehappen.

To the shaft I are attached two pulleys, K L. The pulley K is designedto receive the driving-belt, and the pulley L to receive the belt M,which passes around a pulley, N, attached to the journal of thecutter-head F, to give motion to the said cutter-head.

To a side bar of the frame Gr, near its for ward end, is pivoted theupper end of a bar, 0, the lower end of which is pivoted eccentricallyto a crank-pin of pulley P, which is pivoted to the lower part of theside of the frame B in such a position that the friction-pulley Q,pivoted to the end of the lever B, may come in contact with its face.

With the pulley Q is rigidly connected a pulley, S, to receive adriving-belt for giving motion to the said friction-pulley Q. The leverR is pivoted to the frame A, and its other end projects at the otherside of the said frame,

so that it may be operated upon by the operator with his foot to bringthe pnlleyQ in contact with the pulley P at the same time that he placesa stave upon the rests D. As the pulley Q comes in contact with thepulleyP it revolves the said pulley, drawing down the inner end of theframe G and causing the cutter-head F to cut the croze in the stave.

It is only necessary to change the cutterhead driving-belt when a changein the size of tank is required, (which is seldom done,) the maindriving-belt being driven from a counter-shaft unconnected with themachine.

being crozed, and the swinging frame G,-car rying cutter-head F,substantially as shown and described.

3. In a crozing-inachine, the combination of the rotating cutter-head Fand the swinging frame Gr, whose bearings are made adjustablehorizontally, to allow the said frame to be adjusted longitudinally, asand for the purpose specified.
